圆形电连接器插头、插座安装的注意事项-绅士go
圆形电连接器插头、插座是各种电源接取口，应用极为广泛，所有可移动的用电器具都需经插座、插头接通电源。电气插头、插座种类很多，有单相两眼、单相三眼，也有三相四眼安全插头插座等。
双孔插座可用在外壳不需接地的用电器上，如活动台灯、手电钻、电视机等;三孔插座用在外壳需要接地的电器上，如洗衣机、电冰箱等。单相双孔插座的大额定电流通常只有5a，三孔的有5a、10a、15a、20a等多种，应根据插入该插座的功率大的电器的额定电流选取，插座的额定电流应大于电器的额定电流。
安装、使用圆形电连接器插头、插座时应注意以下几点：
第一、插座应安装在绝缘板上、绝缘盒内或电工用板和圆木上，通常把插座两孔平列安装在建筑物的平面上。
第二、在安装三孔插座时，必须把接地孔眼(大孔)装在上方，且接地接线柱必须与接地线连接，不可借用中性线作为接地线。
第三、相线要接在规定的接线柱上(标有“l”字母)220v电源进入插座一般为“左零右相”。既有双孔又有三孔的插座为组合插座，它多作移动插座使用。其结构和安装与双孔、三孔插座近似。
第四、圆形电连接器插头或插座的额定电流要大于所接的用电器负载的额定电流，不允许用电器的额定电流超过插座上的额定电流。
第五、使用移动插头要保持清洁，注意防潮，以免绝缘损坏发生漏电或短路。
第六、有些单相三眼插头、插座或三相四眼插头、插座在接线时一定要把地线接在有接地符号的接线柱上，并与用电器金属外壳相连接，以确保用电安全。
第七、插头、插座在接线时一定要接触牢靠，相邻接线柱上的电线金属头要保持一定的距离，不允许有毛刺，以防短路。
